Arakawa Lock Gate

The Arakawa Lock Gate manages water levels between different sections of the river, allowing vessels to transit safely through the waterway system in eastern Tokyo.

The lock gate opened on October 3, 2005, replacing older water management structures in an area that previously handled rice and soy sauce transportation by ships.

The lock gate represents Japanese engineering practices in water management, integrating modern technology with traditional river navigation requirements in urban settings.

Visitors can climb to the top of the gate structure for elevated views of the surrounding waterways and observe the lock operation procedures.

Located 300 meters from the historic Kyu Komatsugawa Kōmon structure, the lock facilitates water traffic while providing recreational spaces along its banks.
